Looking at the source, the problem seem to be that the struct stat
member st_mtime is not the same type as time_t.
I've flagged the problematic lines with **:
static time_t last_mtim;
[...]
struct stat statbuf;
if (stat(f, &statbuf) == 0) {
/* If the modification times have changed */
#if defined(HAVE_ST_MTIME_WITH_E) && defined(HAVE_STAT_TIME_T)
#ifdef PCP_DEBUG
if (pmDebug & DBG_TRACE_PMNS) {
fprintf(stderr, "__pmHasPMNSFileChanged(%s) -> %s last=%d now=%d\n",
filename == PM_NS_DEFAULT || (__psint_t)filename == 0xffffffff
? "PM_NS_DEFAULT" : filename,
** f, (int)last_mtim, (int)statbuf.st_mtime);
}
#endif
** return ((statbuf.st_mtime == last_mtim) ? 0 : 1);
[...]
{
struct stat statbuf;
if (stat(fname, &statbuf) == 0) {
#if defined(HAVE_ST_MTIME_WITH_E)
** last_mtim = statbuf.st_mtime; /* possible struct assignment */
#elif defined(HAVE_ST_MTIME_WITH_SPEC)
last_mtim = statbuf.st_mtimespec; /* possible struct assignment */
#else
last_mtim = statbuf.st_mtim; /* possible struct assignment */
#endif
}
}
last_mtime can't be converted to int, compared to statbuf.st_mtime or
get an assignment from statbuf.st_mtime. I'm not quite sure how the
st_mtime membe variable can end up being different from time_t.
Perhaps some missing include file? The stat(2) manual page state that
these are needed:
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
The pmns.c source only include <sys/stat.h>. If that is the solution,
here is a patch:
